LASER SCANS and VIDEO INSPECTION TECHNOLOGY

COKE DRUMSTANKS

CORRODED SURFACES

Coke Drum Bulge Measurement

Scale ±4” with ½” color bands. Labels show spot deviation measurements

Laser Data Conversion / Comparison of Past Coke Drum Scans

2013 3D and 2D Laser Images

Depth / Height = Severity

Example: 1.5” Depth / 6.00” Height = 0.25 Severity. Note: Most severe rating would equal 1.00 (depth = height). Least severe would be 0.01.

Very Portable

Multiple Scans Can Be Performed To Avoid Blind Spots Due

To Obstructions

Quick ( 30 Minutes Per Scan Locations) Depending On Drum

Independent Of Owner Operator Assistance

Economical

3D Modeling of any Vessel, Tank, Column or Piece of Equipment

Requires Detailed Modeling Of Its Distortions

Supports Finite Element Analysis

Support Of API 510 And 653 For Inspections

Volumetric Measurement

Deformation Diagnostics Laser Scan

Raw 3D image

Panametric Laser Photo Image

A Panametric laser photo / image was produced with laser scan results showing the entire ID surface of the coke drum. This image

shows top head nozzle and weld orientations . An as-scanned “unedited” (Raw) 3D image is shown of the drum scanned.

3D Rendition of Floating Roof Tank Floor Scans

Tank Point to Point Measurements

Deviation Measurement Relative to a Standard Shape (Cylinder, Cone, Plane)

3D laser model of tank

Reference cylinder (nominal tank diameter)

Colour deviation map (actual dimensions vs nominal cylinder)

Deviation (colour) scale +50mm to -200mm (+2” to -8”)

Tank Cone Down Floor

Colour scale +50mm (edge) to -235 mm (centre). The object showing near the centre is part of the roof drain system

West Elevation: the blue horizontal line is a wind girder. Scale +100 mm (red) to -100 mm (blue). This data is from external scans, part of the stair

and attachments can be seen at the top-right of the image.

Laser Hand Scanner (High Resolution, High Accuracy, Examines Local Areas with Pitting)

Reference Targets Allow the Hand Held Scanner to Track Its Position

Through the Laser Scan (on the Left) and through a Camera (on the Right)
